That is why after at least three revisions I have no faith in them getting it right anytime soon. If you can't fix an issue like this with amount of failures and the data they have collected it is obvious it will not be fixed anytime soon.
And you are absolutely right you can't make money off of a part that never fails. I was quoted $1,750 to replace a water pump on a 2011 supercharged XJL.

Although a staunch conservative, knowing what I know after more than forty years in the automotive industry, I would strongly endorse anyone who would require a 100,000 mile full warranty on all cars for anything other than tires, brakes, and clutches which should be fully warrantied for at least 40,000 miles.
Unfortunately no political party today, Republicans or Democrats, really give a damn about the average person in the United States, they have all been bought off by special interest groups that serve perhaps one-percent of the population.

You can buy the water pump from rock auto for $90 I am not sure on labor but with where that pump is it should not take more than 2-3 hours to change and burp the system. Lets assume one of their mechanics is making $50/hour. I wouldn't be surprised if their cost was less than $300.
If it was costing them a fortune you would think they would have fixed this long ago so they could save money.

I guess that depends on what it costs them to replace it under warranty compared to what they charge when it is not under warranty. Are they making more off the ones that fail outside of warranty? I highly doubt it costs them $1,750 when it is warranty work.

That is why the government should require a 100,000 warranty on all items but tires, brakes, clutches and batteries, and these should be covered for 40,000 miles, or in the case of batteries, 4 years.

I'm sure we would all welcome any suggestions you may have.

If the manufacturer knows their customer base is ok with replacing faulty parts due to design issues what incentive do they have to improve?

Reading all this with my car (an X350, previous model XJ), on its original waterpump at 92k it strikes me that we do have either a design or a supplier issue. My engine is a 3 litre V6 which, despite the name Jaguar on the engine cover, is a well-known Ford design. I suspect what we have here is a bad batch of pumps. No car maker can afford to get a reputation for poor quality parts like water pumps, not if they want to expand their sales, anyway.

This is a design issue plain and simple some people get hit before others. One of the techs recently said the 3.0 NA motor does NOT use the same water pump as the 3.0 supercharged, 5.0 NA and 5.0 supercharged engines.
It would be interesting to take a pole from the owners who have this water pump on their car, what kind of climate do you live in and how do you let the car cool down.
I live in Houston the pump was replaced on my XFR at 48kish miles the car has spent its entire life here. I have also been opening the hood when I get home to get as much heat away from the engine as possible just in case it is a potential heat issue. A friend of mine just had is crap out on his 2011 supercharged XJL at 65k miles again that car has spent most of its life in the south.
On the more eurocentric jag forums do they have issues with their pumps?

In previous jaguar models, the impeller material was the reason for the premature failure. Plastic or composite vanes didn't hold up to either the coolant heat or didn't react well to the ingredients of the antifreeze. Does anyone know why their particular water pump failed at an early age?

Never use tap water to mix with the anti-freeze, used deionized or distilled water.

I have a 2013 XJ and had a dead battery at 15K miles. I took it in for the battery and they had to replace a leaky water pump,both fuel pumps and the cone on the front of the supercharger. Then 5 days later I heard a noise coming from the front and and again took in and had to replace front axle bearing. I hoping these are in frequent problems

Eleven days before my warranty was to expire, and with just under 40,000 miles on my 2011 XJL 5.0L N/A V-8, the water pump and cross-over pipe started leaking coolant and is now at Scott Jaguar in Charlotte being repaired (under warranty, thank goodness).
Fortunately the low coolant light alerted me before the coolant loss was great enough to cause overheating and therefore before any potential engine damage. I immediately refilled with 70% silicate and phosphate free orange anti-freeze and 30% distilled water, the left-over of both which I stored in the luggage compartment.
Sure enough, before arriving at the dealership 34 miles from my home this morning, I had to stop on the shoulder of Interstate 77 to again replenish the "low coolant".
I'm currently driving a dealer provided XF, and am certainly looking forward to getting back into my XJL with its lush and roomy interior, growling V-8 (which doesn't spend all its time shifting), a far superior standard sound system, and many other niceties.

I just looked back on my 5-24-2015 comment in this thread, and yes I should have also recommended to use silicate and phosphate free anti-freeze, and to use distilled water at a ratio of 70% anti-freeze to 30% water. The reasons?
The main cause of water pump leakage is deposits of silicates and minerals on the opposing flat sealing surfaces of the mechanical face seal that contains the coolant inside the system, thus separating the surfaces, and allowing leakage. These deposits form because the coolant "boils" or evaporates between the sliding and rubbing surfaces of the seal, due to the temperature of the coolant, plus the frictional heat generated by the rubbing surfaces. Solution: minimize the the silicates and minerals in the coolant, plus raise the boiling point of the coolant by having an anti-freeze rich mixture of coolant (which as a side benefit lowers the freezing point even further than a 50/50 mix).

All in all, I'm very pleased with the service I received at Scott Jaguar in Charlotte, and would recommend them to anyone in our area.

My wife's 2011 XJL, 51,238 miles, 5.0L N/A V-8, broke down yesterday on a business trip in South Carolina. Water pump. Repair costs at a local European repair business is $933.96. Before looking at this thread, I thought it was early in the life of the engine for the water pump to go. And before this trip, we had not "smelled" any coolant. The car is garage kept, and usually in such a space the smell of any coolant that's leaking would be evident. Also, 90% of the time just drives it back and forth to work.
I have read Johndahlheimer's comments of the coolant and seals. But mechanically the design of the pump is also an issue I think.
Just so disappointing that such an important part on this car is failing so early.

Rodney,
Glad to see you're back! Hopefully, there was no other damage and it's just a pump replacement. Unfortunately, some other 5.0L owners (mainly in the X150 Forum) haven't been so lucky and overheating caused by water pump failure led to engine damage, including warped heads and worse. See: https://www.jaguarforums.com/forum/x...lready-118826/
Even though you're out of warranty, you might want to call Hennessy Jaguar about getting some consideration from Corporate since the defective water pump is a known issue on your model, even though it has not yet risen to the level of a recall. There are several TSB's. See post #3: https://www.jaguarforums.com/forum/x...r-pump-120768/
Keep us posted, and let us know the outcome. Good luck!
